ToME: the Tales of Maj'Eyal

Was fighting Epoch as a Temporal Warden. When told to go "Meet the Master," just before getting shunted to the mini-level, I got a bug message, but since I seemed to still be playing I continued on. After defeating Epoch and exiting the mini-level where he lived, the game was frozen and the HUD disappeared.

I run Linux, if that's relevant.
